What is SPF? SPF stands for sun protection factor. This rating is used to determine how sunscreens block UVB radiation. SPF 30 blocks 96.7 percent of UVB radiations, and SPF 50 blocks 98.6 percent. Let's discuss SPF in more detail. Here are a few examples of SPF. What are the advantages of SPF?

SPF is the abbreviation for Sunscreen Protection Factor. It shields against UVB rays.

While SPF is a widely used measure of the protection that a sunscreen provides, it's not a complete measurement. The SPF number measures the protection offered by only UVB radiations. Sunscreens are not required by the FDA to protect against UVA Rays, and a majority of sunscreens have been designed to provide UVB protection, and haven't been given much attention to the other Rays.

The SPF of a sunscreen is not directly related to the time spent in the sun, but to how much time it protects against UVB radiation.

The measurement of SPF isn't perfect. The test conducted on humans is conducted under controlled conditions to determine the degree of protection. The intensity of UVA rays can be fixed while the intensity of UVB radiations can change. The intensity of UVB rays varies, and consequently the SPF of a product will depend on how effective it is in protecting against UVB rays.

Although SPF is an excellent indicator of the protection provided by a sunscreen against UVB radiation, it does not guarantee protection from UVA rays. It is recommended to purchase a broad-spectrum sunscreen with an SPF between 15 and 30. The SPF numbers do not indicate quality, but rather an indicator of the effectiveness of sunscreens.

The SPF of a sunblock product is measured under artificial conditions. A sunscreen with a higher SPF can offer more protection from UVA radiation and claim to offer additional advantages.

In-vivo testing is the only way to determine the effectiveness and substantivity.
